Horizontal injection molding machine Mark 6

servo-hydraulicfor PVCfor PET

Overview
The MK6 represents the 6th generation of JetMaster series injection moulding machines. The clamping mechanism, machine base and injection unit have been reinforced to deliver improved efficiency and enhanced operational stability across the JM88–JM668 range.

Stability & Performance
Strengthened platen and tie-bar layout, together with an upgraded injection unit, provide better distribution of clamping stress and smoother injection dynamics to support high-pressure applications and reduced cycle variability.

Precision – Energy Efficient
MK6-series machines use SVP/3 servo-hydraulic technology, delivering up to ~80% energy savings versus older fixed-displacement machines. Precision HydraulicsTM achieves repeatability within 0.05% on critical axes, improving part consistency and yield.

Major Advantages of JM-MK6 Machines

• Low energy consumption: Innovance servo drive system reduces energy use up to 80% and ensures low-noise operation.
• Production flexibility: Increased tie-bar clearance and maximized strokes adapt to a wider range of moulds.
• Redesigned platen: Optimised clamping stress distribution for lighter, faster operation and extended service life.
• Faster mould setup: Redesigned ejector system with SPI standard and space for ejector rods simplifies and accelerates tool changes.
• Improved injection performance: Injection unit with bearing guides smooths dual-cylinder operation and improves stress absorption.
• Shorter cycle times: High-pressure injection and fast speed recovery reduce cycle times.
• Ergonomics: Safety doors and covers designed for easy access during operation and maintenance.
• Low maintenance: Repeatable and reliable production with reduced maintenance needs.

European Specs

• EUROMAP standard hole and ejector patterns (may vary by platen design).
• Standard European components: hydraulic valves (Bosch Rexroth or Vickers), hydraulic pump (Eckerle), linear transducers (Gefran or Novotechnik), electrical components (Siemens, Schneider, Telemechanique, PILZ).
